After receiving a message from our datapump server that drive C was low on disk space, we noticed that under the MDatapump/localsettings/apps/temp folder there was aprox 5 gig in files. We then proceeded to move the temp files off of C to the D drive. We then began to receive the following error on all our processes. Attempted to read or write protected memory, this is often an indication that other memory is corrupt. As we began to restore the temp files back to their original location datapump began to process normally. Can someone tell me if all the temp files have to remain or which ones we have to keep.
